| 4.4.2 | Asymmetric switching
Collisions and collision domain size are two factors that negatively affect the performance of a network. By using LAN switching, you can microsegment the network, thus eliminating collisions and reducing the size of collision domains. Another important characteristic of a LAN switch is how it can allocate bandwidth on a per-port basis, thus allowing more bandwidth to vertical cabling, uplinks, and servers. This type of switching is referred to as asymmetric switching, and it provides switched connections between ports of unlike bandwidth, such as a combination of 10-Mbps and 100-Mbps ports.
